POWER-UP

Turn on the power to the motor.  The MotorSaver

®

 then goes through its restart 

delay and the LED will flash green (see Table 1).  After the restart delay, the 

MotorSaver

®

 will energize its output contacts and the RUN LIGHT will turn solid 

green.  If the contacts do not energize and the RUN LIGHT does not turn solid 

green, then see the TROUBLESHOOTING section.

1.LINE VOLTAGE ADJUSTMENT:  Rotate the LINE VOLTAGE ADJUSTMENT to  

   the nominal three-phase secondary voltage of the potential transformer.

2.TIME DELAY RESTART (RESTART DELAY):  Rotate the RESTART DELAY to  

   the desired position.  The restart delay is the time between the MotorSaver

®

 

   seeing acceptable power and the MotorSaver

®

 closing its output contacts.  The  

   restart delay should be set appropriately for the individual application.   If the  

   RESTART DELAY is in the MAN (manual) position, then the unit will not 

   automatically restart until it is turned out of the MAN position.
